what's going on youtube gs9 here in
0:02
today's video i have great news for
0:04
those of you waiting for a jailbreak
0:06
because out of the blue a brand new
0:08
kernel exploit with full read and write
0:10
primitives has been released and this
0:12
one works on ios 15.1.1 and lower and it
0:15
may even work on 14.8 and stuff like
0:18
that for those of you waiting on 14.8
0:20
14.7 and so on so if you remember back
0:23
in december john ackerblom posted this
0:25
ios 15.2 fixes multiple kernel
0:28
vulnerabilities that can be used for
0:29
local privilege escalation they go on to
0:32
detail where these vulnerabilities are
0:34
or how they can be triggered and stuff
0:36
like that but no code has been posted at
0:38
that time however just a couple of hours
0:40
ago today they posted this quote last
0:42
week i held a presentation at xerocon
0:45
about recent ios kernel vulnerabilities
0:47
and exploitation techniques that haven't
0:49
made it to the spotlight just published
0:51
an exploit for one of the bugs covered
0:53
that i also tweeted about in december
0:55
and they referred to this tweet here
0:57
about 15.2 fixing the bugs and yes sure
1:00
enough there is a github link over here
1:02
with multicast byte copy this is the
1:04
exploit and as you can see over here it
1:06
says it's a kernel exploit with read and
1:08
write primitives for 15.0 up to 15.1.1
1:12
so this is basically a complete full
1:14
exploit not a proof of concept not just
1:16
a bug not just a vulnerability it's a
1:18
full exploit with read and write
1:20
primitives which can directly be used
1:22
for a jailbreak the jailbreak teams like
1:24
turin and uncover and so on can take
1:26
this as it is and put it in their tools
1:29
and they would have a working exploit
1:31
for 15.0 to 15.1.1 on all devices this
1:34
is actually quite important we already
1:37
have another vulnerability another bug
1:39
but this one is also great because it
1:41
also seems to have full kernel read and
1:43
write primitives which is definitely
1:44
usable for jailbreak purposes what's
1:46
even better is that this can also be
1:48
used and adapted for ios 14 which means
1:52
14.8 14.7 14.7.1 and so on as you
1:54
probably remember some of you stayed on
1:56
14.8 or 14.7.1 14.7 and uncover ended up
2:01
not supporting those on some devices
2:03
like the a14 or something and the
2:05
exploit we already have for ios 15 does
2:08
work on ios 15 but doesn't work on 14.
2:11
however this one over here that was
2:13
released today yes that one would be
2:15
usable to update on cover to support
2:17
14.7 14.7.1 14.8 as well as ios 15 up to
2:22
15.1.1 on all devices which is
2:25
definitely great so this is a major
2:27
release in terms of jailbreaking not
2:29
only because of the exploit itself but
2:31
also the techniques inside the exploit
2:34
those are techniques that apparently
2:35
haven't been used a lot in the public
2:38
and they're apparently a little bit new
2:40
or at least not very well known for the
2:42
general public which is great because
2:44
that's exactly what we need as you may
2:46
know from coolstar and many other
2:47
developers many of the techniques we
2:49
used to have that we used to use on
2:51
jailbreaks have died have been patched
2:53
by apple or have been rendered useless
2:56
the fact that new techniques that
2:57
haven't been seen before are being
2:59
burned and put into the public that's
3:01
actually great because it means that we
3:02
can continue working on jailbreaks like
3:04
taurine and uncover without having to
3:06
burn zero day which i doubt any sane
3:09
developer would do because zero day
3:10
exploits cost a lot so yeah that's
3:13
basically the brand new kernel
3:14
vulnerability with read and write
3:16
primitives that's very important because
3:18
it means it can apply patches for
3:20
jailbreak purposes has been indeed open
3:23
sourced on github and not only that new
3:25
techniques as well which could be used
3:27
in order to derive more vulnerabilities
3:29
and more exploits in the future this is
3:31
actually a good day for jailbreak
3:33
purposes and i made thousands of videos
3:35
about vulnerabilities being released
3:36
because that's what i do i cover
3:38
everything that moves in the jailbreak
3:40
community but today today is a good day
3:41
the vulnerability is indeed big so thank
3:44
you for watching i am js now till the
3:46
next time subscribe to stay updated and
